2 Claims.

The present invention relates to water barriers particularly to those atthe feed end of the water-trough from an extruder for cables or thelike.

"Difficulties have been encountered at the feed endof the water-troughfrom extruders in introducing the cable or any other object at the feedend of the water-trough with the minimum loss of water.

It is, therefore, the object of the present invention to provide meansfor providing a water barrier at the feed end of the water-trough.

It is another object of the present invention to provide a water barrierof simple construction which allows easy adjustment and separation ofall elements. a

With these and other objects in View the present invention will becomeapparent and clearly understood in connection with the followingdescription and the drawings, in which:

Figure 1 is an elevational end view of the water barrier;

Fig. 2 is a top view of the water barrier shown in Fig. 1;

Fig. 3 is a sectional view along the lines 3-3 of Fig. 1; and

Fig. 4 is a sectional view along the lines 4-4 of Fig. 1 showing a cableinserted in the water barrier.

Referring now to the drawings the water barrier according to the presentinvention consists of a U-shaped front plate I substantially followingthe end flange 2 of a water-trough 3. The flange 2 and the plate I areequipped with a number of coordinated holes 4 adapted to receive screwbolts (not shown) in order to secure the plate I to the flange 2. Theplate I is further equipped with a number of threaded borings 5 whichreceive wing screws 6 which are adapted for attachment of guide strips Iof L-shaped crosssection to the plate I. On front of the plate I anotherU-shaped plate 8 is provided between the two guide strips I screwed tothe plate I and kept in properly leveled position by tightening the wingscrews 6. The leg portions of the U-shaped plate 8 are equipped with anumber of threaded borings 9 which receive screws I0 which secureanother pair of strips II to the U-shaped plate 8. The top of the baseof the U- shaped plate 8 has a half circular cutout I2 and around thiscutout three threaded borings I3 preferably in triangular arrangementare provided adapted to receive screws I4 the purpose of which will bedescribed later.

Into the open space of the U-shaped plate 8 and held between the plate Iand the strips I I is inserted another substantially rectangularlyshaped plate I5. The bottom of plate I5 has also a half circular cutoutI6 of a diameter corresponding with the diameter of the cutout -I2 inplate 8. By this arrangement of the two cutouts I2 and It the plates 8and I5 provide together a circular opening into the watertrough 3. Theplate I5 is also equipped with three threaded borings I! which receivescrews I8 adapted for a purpose to be described later.-

A smaller substantially rectangularly shaped flexible cover I3 isprovided in front of the bottom of the plate I5, which cover has threeholes 20 in an arrangement corresponding to the three threa'dedborings II of plate I 5. The COVGI'IIB has an extension 2| of a widthcorresponding with the diameter of the circular opening formed by plates8 and I5. The cover I9 is also equipped with a vertical slot 22extending upwardsfrom the center of its lower margin for a lengthshorter than the radius of the circular opening.

A second cover 23 is provided in front of the top of the base of theU-shaped plate 8'covering the half circular cutout of the plate-8. :Thecover 23 is formed exactly like cover I9 except it is not provided withan extension as disclosed before in connection with cover I9. Thus cover23 has also three holes 24 arranged corresponding with the threadedborings I3 in the plate 8. A vertical slot 25 is also provided extendingfrom the center of the upper margin of the cover 23 downwards, however,for a length shorter than the radius of the previously mentionedcircular opening in plates 8 and I5.

The two covers l9 and 23 cover entirely the circular opening formed bythe plates 8 and I5 whereby the extension 2I of the cover I9 overlapsinwards a portion of the upper margin of the cover 23.

Two additional preferably rectangular covers 26 and 2! of the same sizeas the above described cover 23 are provided namely the cover 26 infront of the cover I9 and the cover 27 in front of the cover 23. Bothcovers 26 and 21 have also three holes 28 and 29, respectively,corresponding with the threaded borings I3 and H of the plates '8 andI5, respectively. The upper cover 26 has two slots 30 extending from itslower center at an angle of 45 upwards and the lower plate 21 hascorresponding slots'3I extending from the upper center downwards at anangle of about 45. The covers I9, 23, 28 and 27 are made of rubber,vinylite or any other similar flexible material. In front of the coversagain with three holes 34 in an arrangement corresponding with the threethreaded borings H of the plate 15. The upper plate 32 has further ahalf circularcutout 350i a diameter corresponding with the diameter ofthe half circular cutout in plate H5. The lower metal plate 33 has alsothree holes 36 corresponding with the three threaded borings l3 of theplate '8 as well as a half circular cutout '36 of the same diameter asthe half circular cutout of 'the plate 8.

As stated above the threaded borings l3 and 11, respectively, areadapted to receive screws M and 18, respectively, the screws I4penetrating the holes of the metal plate 33, of the cover 21, and

-;:of :thecover 23 and then to be screwedinto the -.;threaded borings 13of the plate .8, whereas the :screws 18 penetrating thezholes of themetal plate 32,;of the cover 26,.and of the cover l9.and then itolie-screwed into-the threaded borings ll of the :plate 1 5, sothatallcovers and front metal plates *arescrewed to the respectiveplates 8 and 15 by -means of the same screws l4 and 18, respectively.

: -This arrangementleaves a circular opening on xthesoutside of theplate as well as on its inside,

this opening .being closed up by the respective icovers which -.areprovided with slots extending from the center of the circular opening.This arrangement allows .theintrusion of a cable into the trough byopening the-slots .of the different ecovers, the latter providing atight fit around .thecable-which will avoid anyiloss of water out :ofthe, trough.

. The-construction according to the ,present inyention has as aparticular feature that every -oneof'the elements and particularly thecovers which will 'besubjected to wear can easilybe sep- Faratedmandexchanged and also can easily be :;adjusted. ,By providing guides forthe difierent pla1tes it is also possible to adjust the center "of2the;;opening on difierent desired levels.

While I have disclosed the principles of my invention in connection witha single embodiment, it will be understood that this embodiment is givenby way of example only and not as limiting the scope of the invention asset forth in the objects and the appended claims.

What I claim is:

1. A cover forming a water seal while permitting the passage of acylindrical body, comprising two rigid plate members formed with alignedholes, to accommodate said body, and a plurality of flexible diaphragmsclamped between said plate members and formed of two parts each,including a first diaphragm adjacent one of said plate members havingone part which extends substantially to the center of said holes andhaving another part formed with an extension lying within the hole ofsaid one plate and extending across the width of said hole, saidextension overlapping the edge of said one part, and further including asecond diaphragm having two parts with abutting edges, said diaphragms:being formedwith slots extending radially of said holes but less thanthe full diameter thereof, in such a manner that the slots in .saidfirst diaphragm are staggered with respect to :thosein-said-second,diaphragm.

'2. ,A cover according to claim -1 wherein each of said plate memberscomprises two abutting .parts having 1 complementary cutouts :to form-;the said hole.
